So, recently I have read an interesting article about physiograms. I have heard of them before, but never had the chance to produce one. Its defined as unique patterns formed by light in motion. So my curiosity got better of me and I have waited for the dark to construct my experiment. BTW, its best done when everyone is a sleep and your pooch had an extensive walk for lack of distraction 
Here are some samples that I produced. If anyone will be interested how I did it, I will post step by step later on.
Thats it for now..
